Background: Cushing's syndrome due to an ACTH-secreting pituitary tumor is associated with serious morbidity and mortality. As there is no definitive medical treatment, surgical removal of the tumor via the transsphenoidal route remains the first choice. Postoperative hypocortisolemia is recognized as the best indicator of cure. Objective: To report the postoperative outcome and long-term follow-up of patients with surgically treated Cushing disease at the Rabin Medical Center. Methods: We reviewed the medical records of 27 patients with Cushing disease operated on between the period 1990 and 2003. The same experienced surgeon performed all surgeries. Results: Cushing disease accounted for 15% of all pituitary surgeries in our center. The mean age was 46 years, and the female to male ratio was 25:2. Macroadenomas were found in 19% of cases, and a negative MRI in another 19%. The cure rate was 70% overall and 80% when only microadenomas were considered. There were no major perioperative complications. Four out of 8 surgical failures were re-operated, and three achieved cure. After a mean follow-up period of 5.9 years, there was only one recurrence. Conclusion: Our results are in accordance with those reported by others and confirm that in the hands of an experienced neurosurgeon, pituitary surgery constitutes an effective treatment for Cushing disease.
